Frank Herbert's Dune

Frank Herbert's Dune is a 3D video game based on the 2000 Sci Fi Channel miniseries of the same name. As Paul, the son of the Duke Atreides's concubine and heir to the throne, the player must earn the trust and respect from the natives of the desert planet Dune, the Fremen, to ultimately become their prophesied messiah and free them from the desolate conditions of the planet. Done that, there still is the evil Baron Harkonnen to overcome; he, with covert backup from the Emperor, had slaughtered the Atreides family.
